GEARING.

Specification of Letters Patent.

Patented Apr. 29, 1913.

To all whom it may concern:

Be it known that I, Funnucn V. FISCHER, a citizen of the United States,residing at Norfield, in the county of Lincoln and State of Mississippi,have invented a new and useful Gearing, of which the following is aspecification.

This invention aims to provide a novel form of gearing, adapted to beused, primarily, but not exclusively, upon a Windlass o1 winch, wherebythe shafts of the Windlass or winch may be disconnected and be connectedoperatively at will.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of invention herein disclosed can be made within the scope ofwhat is claimed without departing from the spirit of the invention.

In the drawings, Figure 1 is a top plan; Fig. 2 is a side elevation;Fig. 3 is an end elevation; and Fig. 4c is a horizontal section taken onthe line l-4 of Fig. 3.

In carrying out the invention there is provided a supporting structurewhich comprises as fundamental elements, a top plate 1 and a bottomplate 2. These plates 1 and 2 are preferably cast metal, and may be ofany desired thickness. The plates 1 and 2 are spaced apart by tubularposts 3 through which extend tie bolts 4 engaging the plates 1 and 2, tobind the same against the ends of the posts 3. Secured to the lower faceof the bottom plate 2 are a plurality of brackets 5, in which arejournaled supporting wheels 6. Secured to one end of the bottom plate 2is a clevis 7 and other clevises 8 are secured to the other end of thebottom plate. The several clevises 7 and 8 may be employed for drawingthe device about and for anchoring the same, suitable traction means 9being ordinarily connected with the clevises 8.

The invent-ion further includes a primary shaft 10 which carries fixedlyconnected thereto, a drum 11, located between the plates 1 and 2. Thedrum 11 is provided upon its lower end with a ratchet 12. The

- lower end of the primary shaft 10 is journaled in a thrust-bearing 14;carried by the bottom plate 2, and the upper end of the primary shaft isjournaled in a bearing 1 1,

which may be secured to the upper face of the top plate. Fixed to andupstanding from the bottom plate 2 is a fulcrum bracket 15 upon which ispivotally supported a lever 16, having at one end a pawl 17 adapted toengage the ratchet 12 of the drum 11. Secured to the upper end of theprimary shaft 10 is a main pinion 18 located above the top plate 1.

A secondary shaft 19 is shown, the same being supported for rotation ina thrust bearing 20 secured to the bottom plate 2, the upper end of thesecondary shaft 19 being journaled in a bearing 21 which is carried bythe top plate 1. Secured to the upper end of the secondary shaft is asecondary pinion 22 which is peripherally spaced from the main pinion18. Supported for swinging movement upon the secondary shaft 19, abovethe secondary pinion 22 is a lever 23,

carrying a depending stub shaft 24 upon.

which is journaled an auxiliary pinion 25. The auxiliary pinion 25,meshes with the secondary pinion 22. Superposed upon the lever 23 andsecured to the upper end of the secondary shaft 19 is a head 26,constituting means for holding the lever 23 in place, the head 26, inits turn, being held upon the shaft 19 by means of a nut 26?. The head26 is equipped with outstanding, laterally extended arms 27, providedwith sockets 28, adapted to receive sweep bars.

A latch 29 is hinged as indicated at 30, to the free end of the lever 23for vertical swinging movement, the latch 29 being equipped with adepending stud 31, adapt-ed to register in one of a pair of openings 32,formed in an extension 33 of the top plate 1. Intermediate its ends, thelatch 29 is curved as indicated at 34, to extend across the periphery ofthe auxiliary pinion 25.

In practical operation, the cable is connected with the drum 11, and thelever 23 is swung with the secondary shaft 19 as a fulcrum, until theauxiliary pinion 25 meshes into the main pinion 18. The latch 29 is thenswung vertically until the stud 31 engages in one of the openings 32, tohold the pinions 25 and 18 in mesh. Thereupon, when rotatory movement isimparted to the secondary shaft 19 through the medium of the sweepsupporting members 28, rotation will be imparted to the secondary pinion25 meshing into and driving the main pinion 18, the latter impartingrotatory movement to the primary shaft 10 and to the drum 11. To breakthe drive, the free end of the latch 29 may be lifted, withdrawing thestud 31 from the opening 32 in which it is mounted, whereupon the lever23 may be swung laterally, the auxiliary pinion 25 being moved out ofmesh with the main pinion 18 whereby the primary shaft 10 and the drum11 are actuated. The drum 11 is then free to rotate, and the cable orchain may be paid out readily and rapidly, and drum 11 and the pinion 18rotating independently of the secondary shaft 19 and accessory parts. Itwill therefore be seen that the draft animals may be permitted to stand,during the time that the chain or cable is being paid out.

Obviously, the drum 11 may be held against rotation, to retain thetension in the cable, by the lever 16 and its pawl 17, the constructionbeing such that the pawl 17 normally remains engaged with the ratchet12. However, by pressing the free end of the lever 16, the pawl 17 maybe disengaged from the ratchet 12, thereby permitting rapid reverserotation of the drum, when the pinions 18 and 25 are out of mesh.

Having thus described the invention what is claimed is In a device ofthe class described, a supporting structure; a main shaft journaled forrotation therein; a main pinion secured to the main shaft; a secondaryshaft journaled'in the supporting structure; a secondary pinion carriedby the secondary shaft and out of mesh with the main pinion; a leverfulcrumed on the secondary shaft for movement parallel to the plane ofrotation of the pinions; an auxiliary pinion journaled on the lever andbeing continuously in mesh with the secondary pinion, the auxiliarypinion being adapted to mesh into the main pinion when the lever isswung on the secondary shaft; a latch pivoted to the lever for movementat right angles to the plane of rotation of the pinions; andinterengaging elements on the latch and upon the supporting structurefor holding the auxiliary pinion in and out of mesh with the mainpinion; the latch being curved to extend across the periphery of theauxiliary pinion, thereby permitting the latch to rest upon thesupporting structure and permitting the interengaging elements tocooperate.

In testimony that I claim the foregoing 'as my own, I have heretoaflixed my signature in the presence of two witnesses.
